Natasha thinks she doesn't want to be having this moment with Daniel. She believes the "poetic heart" isn't trustworthy, as it says that all a person needs are love and dreams and totally neglects the fact that people need food and shelter. Regardless, Natasha feels like her heart wants Daniel, no matter how stupid he's being. She wonders if there is such a thing as destiny, but walks away without taking his hand.
Natasha's reasoning provides more evidence for the assertion that she leans on reason because she wholly understands—and has experienced firsthand—the consequences of not having money. In her defense, studies have shown that money problems are some of the most destructive problems within romantic relationships.
